Many people have questions about the differences between DVD formats and the compatibility of the discs in different players and recorders. Hopefully this can answer some of those inquiries.
The two are competing technologies that use different formats. No single company owns “DVD” and both technologies have their differences and advantages. DVD+R allows multiple layers for per disc while DVD-R only allows one layer. Multi layer DVD+R allows for more capacity than DVD-R, therefore it is more expensive. Also, DVD+R DL/+RW format offers more space for anyone who wants to record their own movies and audio and play in their own computer but not in a DVD or BD-r player.
DVD-R and -RW are officially approved by the standards group DVD Forum, which was founded by Mitsubishi, Sony, Hitachi, and Time Warner. DVD+R and +RW formats are not approved by the DVD Forum standards group, but instead the DVD+RW Alliance. The DVD+RW Alliance is supported by Sony, Yamaha, Philips, Dell, and JP. According to the DVD Alliance, using a DVD+R/+RW recorder will let you instantly eject without having to wait for finalized formatting. Also, it allows the ability to record one DVD partially on different recorders, such as a PC and then on a TV. It will let you simultaneously record on parts of a DVD that have been previously formatted, and allows for enhanced ability to edit file names on the disc. Lastly, it claims 100% compatibility with all other DVD players. We at http://www.cameratodvd.com/ are not finding that to be true. Older DVD players may have a problem playing them. We also find there are some players that like only the DVD+R.
When you transfer video or make video for others to view, here is the bottom line. You can use either DVD+R or DVD-R and make sure it has been finalized.
“Why won’t my DVD player read my DVD?”
If your DVD won’t play in your DVD player, remove the disc and look at the back. If it has many scratches and smudges then that is most likely the reason for the read error. DVDs can be cleaned/repaired to some extent. Also, a damaged DVD may play in one player but not in another. It’s always a good idea to make an extra copy of your DVD and keep the master in a safe place, just in case.
“I had my VHS tape copied to DVD and when I got it home, it won’t play. If it does play, it plays badly. Why?”
It might be that your player is not compatible with either DVD-R or DVD+R. Some older models were only made to play one format and not the other. On the other hand, your DVD player may not be able to play any kind of recordable DVD media, which means that neither DVD-R or DVD+R can be read. Be sure to read the manual that came with your player to find out for sure. Most newer models of DVD players are built to read both formats. There is a difference between the DVDs that you might rent or buy from a store and the ones that you can record on, like DVD-R/DVD+R. Movies that are purchased are most likely on DVD-5 or DVD-9. Try the recorded DVD in a player that is made to play DVD-R/DVD+R discs. If it plays well there, then it’s most likely the player that is the issue.
